Apparatus and Method for Selecting Uplink Transmission Beams in Wireless Communication System

2. The method of claim 1, wherein the configuration information is received via a higher layer signaling.

4. The method of claim 1, wherein, in case that the selection of the uplink transmission beam of the UE without the uplink beam sweeping is available, the uplink transmission beam is selected based on downlink measurements.

5. The method of claim 1, wherein each of the SRSs for the uplink beam search corresponds to one corresponding antenna.

7. The method of claim 6, wherein the configuration information is received via a higher layer signaling.

9. The method of claim 6, wherein, in case that the selection of the uplink transmission beam of the UE without the uplink beam sweeping is available, the uplink transmission beam is selected based on downlink measurements.

10. The method of claim 6, wherein each of the SRSs for the uplink beam search corresponds to one corresponding antenna.

12. The UE of claim 11, wherein the configuration information is received via a higher layer signaling.

13. The UE of claim 11, wherein the at least one processor is configured to receive, from the base station via the at least one transceiver, feedback information for indicating the uplink transmission beam of the one or more uplink transmission beams on the UE.

14. The UE of claim 11, wherein, in case that the selection of the uplink transmission beam of the UE without the uplink beam sweeping is available, the uplink transmission beam is selected based on downlink measurements.

15. The UE of claim 11, wherein each of the SRSs for the uplink beam search corresponds to one corresponding antenna.

17. The base station of claim 16, wherein the configuration information is received via a higher layer signaling.

18. The base station of claim 16, wherein the at least one processor is further configured to transmit, to the UE via the at least one transceiver, feedback information for indicating the uplink transmission beam of the one or more uplink transmission beams on the UE.

19. The base station of claim 16, wherein, in case that the selection of the uplink transmission beam of the UE without the uplink beam sweeping is available, the uplink transmission beam is selected based on downlink measurements.

20. The base station of claim 16, wherein each of the SRSs for the uplink beam search corresponds to one corresponding antenna.
